HANGER FOR WIRES Specification of Letters Patent.

Application iled July 17, 1902. Serial No. 115,977.

To all whom' it may concern:

Be it known that I, FRANK L. SEssIoNs, a citizen of the United States, residing at in the lcounty of Franklin and State of Ohio, have invented certain new and useful Improvements in Hangers for Wires, of which the following is a speci- .cation, reference being had therein to the accompanying drawing. f

This invention relates to an improved device for suspending wires, being particularly adapted for the support of electric wires from a body above the wire, as for instance from the roof of an -entry in a mine.

Figure 1 shows partly in section and partly in side elevation a wire hanging mechanism embodying my improvements. Fig. 2 shows in section the insulating hanger. Fig. 3 shows in side elevation the fastening or roof bolt, the roof of the mine being shown in section. Fig. 4 shows a modified form of insulating hanger. Fig. 5 shows. partly in section and partly in side elevation a wire hanging mechanism with another form of insulating hanger. Fig. 6 shows in side elevation the metallic part of the hanger which is below the fastening bolt. Fig. 7 is a bottom plan View of the same, and Fig. 8 `is a vertical section of the same. Figs. 9 to l2 show details. Fig. 13 shows in side elevation the metallic which is below the fastening bolt in Fig. l.

l have illustrated the invention as applied to the roof of a coal mine, the'latter being conventionally illustrated in section.

The fastening device which supports the hanger is indicated as a whole by A, B indicating the yhanger and C the Wire carrier. The fastening device A, is composed of two parts A and A2, these when fitted together being at most of their transverse lines substantially circularin section and constituting a ,plug or pin adapted to be inserted into an aperture drilled in the roof of the mine for their reception. The part A has a shank E which is smooth upon its exterior surface; but the part A2 is formed with outwardly or spurs D, D which are adapted to be pressed or embedded in the coal. The part A2 is first inserted linto the hole and then the part A. is driven in by the side of it, and being `somewhat taperi it serves somewhat as a wedge tol force the part of the hanger spurs or projections D' of the part A2 into the material at the side'of the aperture, thus preventing the withdrawing of the fastener as a whole without the application of great force. The parts A, A2 are each formed with ya shoulder or ange as at F, F, which bear against the coal at the outer end of the socket or aperture therein. rl`he part A2 has a screw threaded extension or stem G for supporting the hanger.

The hanger B is shown as comprising the upper metal part H, the lower metallic part l', and the insulating part J. The part H is formed with a neck h having a threaded v aperture h', the cover or guardr` iange k2 having an annular recess or groove N, the downwardly extending wall its having apertures h4 and the inwardly turned lip or flange it, there being an aperture in the latter at its. The lower metallic part I can be of the nature of /a bolt, having a head t', the shank si', and the threaded loweriend The head is of a diameter slightly smaller than that of the hole at 71.6 and may be recessed at t as shown. The terial J is inserted in such a way as to lill the chamber which surrounds the head i and the upper part of the shank z", and the orilices or apertures h4, the insulation extending down through the aperture h6 and then around the outsideof the parts and h3 and filling the annular recess 71.7. The insu- I lation is therefore retained in place by the lip its, the walls of the aperture 71.4 and of the annu-lar recess It?. The insulation fills the recesses 4 and serves to prevent the rotation of lthe metallic part l within the hanger.

1 ln the modified form of device shown in Figs. 5 to 8 the part H is formed with the neck having a threaded aperture t, the -cover or guard iange 71.2, the cross plate it, the downwardly extending wall ht and the inwardly turned lip or flange h5, there being an aperture in -thelatter at h6 relatively oblong in shape. The vhead z' of the metallic Apart l is on one diamter larger than the shorter diameter of the hole at it, the larger diameter of this hole is suli'cient to allow the insertion of the head which is afterward given a .quarter turn before the insulating material is inserted. fBeing in some dimensions larger than the aperture 7L the downward strain is transmitted from the part l to the part H in such a way as to relieve insulating mathe insulating material from excessive stress. In this form of device the insulat-ing material likewise `lills the central chamber, eX tending down through the aperture LG and then down and around the outside parts h4 and r", and inward somewhat over the plate It, the. shield flange or guard h2 covering more or less of the insulation.

In Fig. el is shown still another modifica# tion of the hanger in that here the shield or guard 11,2 is dispensed with. y The insulation .l may be formed of any of the several now well known materials, and inserted or .molded in place by any of the methods that are understood for this purpose.

The wire carrier at C is connected to the threaded end or' the downward projecting metal part l, and is oi' such shape and charactor as to suitably support the wire, requiring however ino detailed description here as any of the numerous styles of carrier can be employed.

A, hanger of the character l have selected to describe is for many purposes superior to any with which l am acquainted. ln mines, such as coal mines, it is :frequently desirable to su port wires as close as possible to the roof lgiecause of the reduced height of the rooms, and when the parts are constructed and arranged in the way l have described an insulated support is provided which projects but two or three inches :trom the roof surtace. Again it is frequently necessary to temporarily suspend wires, as for instance in rooms or chambers where limited operations are to be performed for the time being; and for such places it is desirable that suspending devices be provided which shall be oit reduced cost and which can bequickly put in place or withdrawnu But a single holt or fastening device ik is required with the present construction, whereas it has been customary to employ hangers orp such. nature as that two Yfasteners hadv to be combined with each hanger, this not only increasing the cost incident to the devices, but also the labor and expense incident to putting them in place. By forming the part H with the upwardly extending neck It having an internal threaded socket adapted 'to fit the downwardly projecting stem G a single pin er fastener can be used and by securing the threaded rod or bolt l in 'the manner described the wire carrier can also be ,fastened by a single support.

VI' hat l claim is :w
